研究者们在郴州西山枞树板地区震旦系浅变质碎屑岩中，首次厘定出近东西（北西）向的褶皱构造—山河复背斜的存在，并阐述了近东西向褶皱和近南北向褶皱的特征及其复合叠加类型。最后指出近东西向背斜形成于加里东期，近南北向褶皱形成于印支期。
In the Sinian epithermal clastic rocks in the Firshum plate of the Xishan Mountain in Chenzhou, the authors determined the existence of the nearly east-west (northwesterly) fold structure - the Shanhe anticlinorium for the first time and elaborated the near-east-west fold and nearly north-south Characteristics of folds and their types of composite overlays. Finally, it is pointed out that the Near-East-West anticline was formed in the Caledonian period and the Near North-South fold was formed in the Indosinian Period.
